Losing hot water is disruptive in a way few plumbing problems match. Whether your tank is leaking from a failed anode rod, your pilot won't stay lit, your electric element has burned out, or your tankless unit is flashing an error code β Masters Plumbing Service's water heater techs in Galveston, TX arrive with diagnostic tools and replacement parts to resolve it in one visit.

Water heater work involves gas lines, electrical systems, and pressure vessels β it isn't a DIY project or a job for a generalist. Our techs carry certifications specific to gas appliance work in TX.
Component-level testing takes 10β15 minutes and produces a clear diagnosis β not a guess that leads to replacing the wrong part.
For tankless units, we stock igniter assemblies, flow sensors, and descaling supplies for the major brands common in Galveston homes.
We don't recommend replacement to sell a unit. We work through the math with you openly so the decision is yours.
Every water heater installation in TX must meet current plumbing and mechanical codes β expansion tank where required by closed-loop systems, T&P discharge piped within 6 inches of the floor, correct flue sizing for gas units. We pull permits where required and schedule inspections.
Our techs are trained on all major residential water heater types and brands. Here's how we approach each category.
Thermocouple millivolt output drops below the 25mV minimum the gas valve needs to stay open well before the pilot stops working entirely. Regular output testing catches this before a cold shower.

A failed upper element causes loss of hot water entirely. A failed lower element produces hot water but in smaller volume. Knowing which symptom you're experiencing before we arrive helps us confirm the likely failure quickly on-site.
Scale buildup in the heat exchanger is the leading performance issue in tankless units in hard-water areas. We perform a citric acid descaling flush through the heat exchanger using flush kit ports β restoring flow rate and heating efficiency without replacing the unit.
A T&P valve that drips constantly, won't reset after testing, or shows visible corrosion needs immediate replacement β it's failing in the closed position, removing the safety protection it provides. We replace the valve with a listed unit rated for the tank's BTU input and install or verify the discharge piping before leaving.
Anode rods in Galveston areas with hard water or water softener systems deplete faster than the national average. We check anode condition whenever we have the tank open for any other service β it adds 5 minutes and can add years to the unit's service life.

We carry 30-, 40-, and 50-gallon gas and electric units on the truck for same-day installation in Galveston. Tank-to-tankless conversions are also available where the existing infrastructure β gas line capacity and electrical circuit β supports the upgrade.
Here's what a Masters Plumbing Service water heater service call looks like in Galveston, TX.
Knowing the fuel type, tank size, and approximate age also helps pre-load relevant parts before leaving the shop.
We test the specific components implicated by your symptoms β thermocouple output for gas units, element continuity for electric units, error code analysis for tankless. This focused approach produces a clear diagnosis in 15β20 minutes rather than a vague 'it needs replacing' recommendation.
You receive a flat-rate quote for the repair and, where relevant, a replacement option with installed price for comparison. We walk through the numbers β repair cost vs. unit age vs. replacement cost β and let you decide with full information.
Approved repairs happen immediately. For replacements, we drain and disconnect the old tank, install the new unit with proper flex connectors and expansion tank where required, verify the flue or venting, and test the unit through a full heat cycle before leaving.
Our 11-year-old gas water heater got a fair honest assessment: the tech showed us the repair cost vs. a new unit with installation and let us decide. We replaced it. Correct expansion tank installed, permit pulled, inspection passed. Everything by the book.
{Electric water heater wouldn't recover β 10 minutes of hot water then cold. Masters Plumbing Service's tech identified the lower heating element had failed, drained the tank, replaced the element and lower thermostat while he was in there, and restored full recovery capacity. Explained the difference between upper and lower element function which I'd never understood.|T&P valve dripping continuously. Tech identified it wasn't just thermal expansion but a valve that had corroded open. Replaced the valve, re-routed the discharge pipe to code, verified tank pressure was in normal range. All in under 2 hours.}
Tankless Navien unit throwing error code 027 β heat exchanger overtemp. Tech explained that's almost always scale buildup restricting flow. Performed a citric acid descaling flush through the service ports, restored normal flow. Unit's been running clean ever since. Much cheaper than I expected and no replacement needed.
